It was reported this morning that the SEC had opened an investigation into possible insider trading in connection with the acquisition by Berkshire Hathaway of H.J. Heinz Co., and here's the official announcement from the SEC:

The Securities and Exchange Commission today obtained an emergency court order to freeze assets in a Zurich, Switzerland-based trading account that was used to reap more than $1.7 million from trading in advance of yesterday’s public announcement about the acquisition of H.J. Heinz Company.

In a complaint filed in federal court in Manhattan, the SEC alleges that prior to any public awareness that Berkshire Hathaway and 3G Capital had agreed to acquire H.J. Heinz Company in a deal valued at $28 billion, unknown traders took risky bets that Heinz’s stock price would increase. The traders purchased call options the very day before the public announcement. After the announcement, Heinz’s stock rose nearly 20 percent and trading volume increased more than 1,700 percent from the prior day, placing these traders in a position to profit substantially.

The SEC alleges that the unknown traders were in possession of material nonpublic information about the impending acquisition when they purchased out-of-the-money Heinz call options the day before the announcement. The timing and size of the trades were highly suspicious because the account through which the traders purchased the options had no history of trading Heinz securities in the last six months. Overall trading activity in Heinz call options several days before the announcement had been minimal.

The emergency court order obtained by the SEC freezes the traders’ assets and prohibits them from destroying any evidence.
